2024 onion growing challenges

Maxstim’s 2024 UK onion trials faced unprecedented weather challenges, testing the resilience of both crops and growers. Despite these adversities, the trials produced significant results, offering critical insights into crop management, resilience strategies, and the potential of innovative solutions like biostimulants to enhance productivity.

Adverse conditions put growers to the test

The season began with prolonged wet weather, drastically reducing workable days for field operations. Many growers were forced to plant under suboptimal soil conditions, adversely affecting crop establishment and root development. The optimal drilling window— February to mid-March—was critical for both red and brown drilled onions in these trials, but time pressures and reduced working days forced some operations to proceed under less-than-ideal conditions.

Yield improvements despite setbacks

Despite these operational challenges, the trials achieved a 3.6% increase in yield compared to standard practices. This outcome demonstrates the capacity of growers to innovate and adapt under even under adverse conditions.

Key scientific insights from the trials

The trials provide important lessons for onion cultivation:

Timing is critical: The February-to-March drilling window is critical for maximising yields, even in less-than-ideal weather conditions.
Weather adaptability is vital: Growers must remain flexible, responding to soil conditions and available field days with agility to mitigate risks.
Resilience drives success: The trials underscore the importance of persistence, technical expertise, and collaboration in overcoming environmental and operational challenges.

Results from the Netherlands

In Zeeland, Netherlands, trials showcased the potential of Maxstim’s complex biostimulants to counteract weather-induced challenges. Conducted by De Rusthoeven Delphy on behalf of a major onion-growing company, the trials highlighted the comparative benefits of Maxstim-treated plots against untreated controls.

Treated vs. untreated plots

Leaf growth: Treated onions demonstrated enhanced leaf length and size, boosting photosynthetic efficiency and overall plant vitality.
Root development: Maxstim-treated crops showed longer, denser roots, improving nutrient uptake and anchorage.
Bulb size and uniformity: Treated plants consistently produced larger, more uniform bulbs—a key factor in commercial onion farming.

These physiological improvements directly contribute to increased crop yield and quality, even under delayed planting conditions.

Implications for growers: Innovation in action

The combined results from the UK and Netherlands trials emphasise the need for resilient, adaptable strategies to combat unpredictable weather. As climate unpredictability increases, the insights from the 2024 trials underscore the critical role of innovation and adaptability in modern agriculture.

By integrating advanced solutions like Maxstim’s complex biostimulants into crop management protocols, growers can ensure higher productivity and quality, even in adverse conditions.
